Ten years of infant mental health in the Netherlands:Who are the clients?
Background: Infant Mental Health (IMH) is a topic of current interest that emerged over the past decades, concerned with alleviating suffering and enhancing the social and emotional competence of young children. Worldwide there is increasing recognition of infant psychopathology meriting intervention. However, there are still limited data regarding the prevalence of psychiatric disorders and sociodemographic characteristics of these youngest of patients in clinical settings. Aim: This large, descriptive study aims at presenting the socio-demographic and clinical characteristics of infants referred consecutively to three outpatient Infant Mental Health teams in the Netherlands between September 2000 and July 2013. Methods: The medical records of 783 infants were retrospectively examined and the data were collected from paper and electronic patient files. Clinical and socio-demographic characteristics were categorized in child factors, developmental milestones, family factors and clinical outcome measures (DSM-IV, DC:0-3R, WIPPSI-III, SON-R 2œ-7). Results: Our sample showed significantly more boys (543, 69%) than girls (240, 31%) being referred to the Infant Mental Health teams. Most children were referred when they were four or five years of age, both boys and girls. Mean duration of treatment was about a year and a half (20.34 months, SD 18.87) and most reported diagnoses were ADHD/behavioral disorders, ASS and disorder in infancy/childhood NOS. Familial psychiatric disorders were reported in 242 families (41%). These findings are discussed in the light of earlier research
Prediction of Long-Term Sickness Absence Among Employees with Depressive Complaints
Introduction To study the properties of a screening instrument in predicting long-term sickness absence among employees with depressive complaints. Methods Employees at high risk of future sickness absence were selected by the screening instrument Balansmeter (BM). Depressive complaints were assessed with the depression scale of the Hospital Anxiety and Depression Scale. The total study population consisted of 7,401 employees. Sickness absence was assessed objectively and analyzed at 12 and 18Â months of follow-up using company registers on certified sick leave. Results The relative risk (RR) for long-term sickness absence, for employees at high risk versus not at high risk, was 3.26 (95% CI 2.54â4.22) in men and 2.55 (1.98â3.35) in women, when the BM was applied in the total study population. The RR of long-term sickness absence of employees with depressive complaints compared with employees without depressive complaints was 3.13 (2.41â4.09) in men and 2.45 (2.00â3.00) in women. The RR of long-term sickness absence for the BM applied in employees with depressive complaints was 5.23 in men and 3.87 in women. When the BM with a cut-off point with a higher sensitivity was applied in employees with depressive complaints, the RR for long-term sickness absence was 4.88 in men and 3.80 in women. Conclusions The screening instrument Balansmeter is able to predict long-term sickness absence within employees with depressive complaints. The total prediction of long-term sickness absence proved better in employees with depressive complaints compared with employees of a general working population
Functional Gene-Expression Analysis Shows Involvement of Schizophrenia-Relevant Pathways in Patients with 22q11 Deletion Syndrome
22q11 Deletion Syndrome (22q11DS) is associated with dysmorphology and a high prevalence of schizophrenia-like symptoms. Several genes located on chromosome 22q11 have been linked to schizophrenia. The deletion is thought to disrupt the expression of multiple genes involved in maturation and development of neurons and neuronal circuits, and neurotransmission. We investigated whole-genome gene expression of Peripheral Blood Mononuclear Cells (PBMC's) of 8 22q11DS patients and 8 age- and gender-matched controls, to (1) investigate the expression levels of 22q11 genes and (2) to investigate whether 22q11 genes participate in functional genetic networks relevant to schizophrenia. Functional relationships between genes differentially expressed in patients (as identified by Locally Adaptive Statistical procedure (LAP) or satisfying p<0.05 and fold-change >1.5) were investigated with the Ingenuity Pathways Analysis (IPA). 14 samples (7 patients, 7 controls) passed quality controls. LAP identified 29 deregulated genes. Pathway analysis showed 262 transcripts differentially expressed between patients and controls. Functional pathways most disturbed were cell death, cell morphology, cellular assembly and organization, and cell-to-cell signaling. In addition, 10 canonical pathways were identified, among which the signal pathways for Natural Killer-cells, neurotrophin/Trk, neuregulin, axonal guidance, and Huntington's disease. Our findings support the use of 22q11DS as a research model for schizophrenia. We identified decreased expression of several genes (among which COMT, Ufd1L, PCQAP, and GNB1L) previously linked to schizophrenia as well as involvement of signaling pathways relevant to schizophrenia, of which Neurotrophin/Trk and neuregulin signaling seems to be especially notable
Behavioral outcome effects of serious gaming as an adjunct to treatment for children with attention-deficit/hyperactivity disorder: a randomized controlled trial.
Lower striatal dopamine D2/3 receptor availability in obese compared with non-obese subjects
Background: Obesity is a result of a relative excess in energy intake over energy expenditure. These processes are controlled by genetic, environmental, psychological and biological factors. One of the factors involved in the regulation of food intake and satiety is dopaminergic signalling. A small number of studies have reported that striatal dopamine D-2/D-3 receptor [D2/3R] availability is lower in morbidly obese subjects. Methods: To confirm the role of D2/3R in obesity, we measured striatal D2/3R availability, using [I-123]IBZM SPECT, in 15 obese women and 15 non-obese controls. Results: Striatal D2/3R availability was 23% (p = 0.028) lower in obese compared with non-obese women. Conclusion: This study is an independent replication of the finding that severely obese subjects have lower striatal D2/3R availability. Our findings invigorate the evidence for lower striatal D2/3R availability in obesity and confirm the role of the striatal dopaminergic reward system in obesit
Cognitive deficits in childhood, adolescence and adulthood in 22q11.2 deletion syndrome and association with psychopathology
22q11.2 Deletion Syndrome (22q11.2DS) is associated with high risk of psychiatric disorders and cognitive impairment. It remains unclear to what extent key cognitive skills are associated with psychopathology, and whether cognition is stable over time in 22q11.2DS. 236 children, adolescents and adults with 22q11.2DS and 106 typically developing controls were recruited from three sites across Europe. Measures of IQ, processing speed, sustained attention, spatial working memory and psychiatric assessments were completed. Cognitive performance in individuals was calculated relative to controls in different age groups (children (6â9 years), adolescents (10â17 years), adults (18+ years)). Individuals with 22q11.2DS exhibited cognitive impairment and higher rates of psychiatric disorders compared to typically developing controls. Presence of Autism Spectrum Disorder symptoms was associated with greater deficits in processing speed, sustained attention and working memory in adolescents but not children. Attention deficit hyperactivity disorder in children and adolescents and psychotic disorder in adulthood was associated with sustained attention impairment. Processing speed and working memory were more impaired in children and adults with 22q11.2DS respectively, whereas the deficit in sustained attention was present from childhood and remained static over developmental stages. Psychopathology was associated with cognitive profile of individuals with 22q11.2DS in an age-specific and domain-specific manner. Furthermore, magnitude of cognitive impairment differed by developmental stage in 22q11.2DS and the pattern differed by domain
Transitional psychiatry in the Netherlands:Experiences and views of mental health professionals
BACKGROUND: Psychopathology manifests itself primarily in late adolescence and continues into adulthood. Continuity of care is essential during this phase of life. The current care service distinguishes between child/adolescent (CAMHS) and adult mental health services (AMHs). The separation of services can interfere with the continuity of care. AIM: To map professionals' experiences of and views on the transition and associated problems that young people can experience as they are transferred from CAMHS to AMHS. METHOD: We distributed an online questionnaire among professionals providing mental health care to young people (aged 15-25) with psychiatric problems. RESULTS: The questionnaire was completed by 518 professionals. Decisions relating to transition were generally based on the professional's own deliberations. The preparation consisted mainly of discussing changes with the adolescent and his or her parents. The majority of transition-related problems were experienced in CAMHS, particularly with regard to collaboration with AMHS. Respondents were of the opinion that the developmental age ought to be the determining factor in the decisionmaking process with regard to transition and they considered it important that developmentally appropriate services should be available in order to bridge the gap. CONCLUSION: Professionals in CAMHS and AMHS are encountering problems in preparing the transitional phase and in organising the required structural collaboration between the two separate services. The problems relate mainly to coordination, communication and rules and regulations. Professionals are keen to improve the situation and want to see greater flexibility. In their view, there should be a wider range of specialised facilities for young people, enabling them to benefit from transitional psychiatry.</p
The association between smoking behaviour, social cognition and social functioning in patients with a non-affective psychotic disorder:A prospective follow-up study
INTRODUCTION: In patients with psychotic disorders, both tobacco smoking and deficits in social cognition and social functioning are highly prevalent. However, little is known about their relationship in psychosis. The authors sought to evaluate the multi-cross-sectional and longitudinal associations between tobacco smoking, social cognition and social functioning in a large prospective study. METHODS: This study was performed within the Genetic Risk and Outcome of Psychosis (GROUP) Study, a cohort study conducted in patients with non-affective psychosis (N = 1074), their unaffected siblings (N = 1047) and healthy controls (N = 549). At baseline, three years and six years of follow-up, data on tobacco smoking (using the Composite International Diagnostic Review), social cognition (emotion processing and theory of mind) and social functioning were collected. To assess associations between tobacco smoking and social cognition or social functioning, multivariate linear mixed-effects models and multiple linear regression models were used. Bonferroni correction for multiple testing was applied. RESULTS: A significant positive association was found between smoking and emotion processing (as part of social cognition) in the patient group (estimate = 1.96, SE = 0.6, p = 0.003). However, smoking was significantly negatively associated with participating in pro-social activities compared with smoking (estimate = 2.55, SE = 0.9, p = 0.004). Change in smoking behaviour was not associated with social cognition or social functioning in the longitudinal analyses. CONCLUSION: Findings indicate that smoking patients with a non-affective psychotic disorder slightly outperformed their non-smoking peers on a task on social cognition, but participated less in pro-social activities. Commencement or cessation of smoking was not related to social cognition or functioning
24hour heart rate variability in shift workers: Impact of shift schedule
Abstract: 24-Hour Heart Rate Variability in Shift Workers: Impact of Shift Schedule: L.G.P.M. van AMELSVOORT, et al. Department of Epidemiology, Maastricht University-Disturbance of the circadian pattern of cardiac autonomic control by working at night when the physiological system anticipates rest could explain part of the elevated cardiovascular risk in shift workers. Analysis of Heart Rate Variability (HRV) is a non-invasive tool to estimate disturbances of the cardiac autonomic control. To assess the influence of working at night on cardiac autonomic control, HRV levels were determined in shift workers. 24-h ECG recordings were made during a day on morning shift and a day on night shift. Within person differences between a morning and a night shift were calculated. Possible modification of the reported effects by the shift schedule was determined. Significantly elevated mean %LF during sleep was found on a day worked on night shift compared with a day on day shift (%LF + 3.04, P<0.01). Type of shift schedule was found to be a significant modifier of this effect. The difference in %LF between the night and day shift for the different shift schedules apart were: + 0.88% for the workers in the fast forward rotating shift, + 3.06% for the fast backward rotating shift, + 6.15% (P<0.001) for the medium speed backward rotating shift and + 1.18% for the shift workers without a regular shift schedule. The results suggest an increased sympathetic dominance during a night shift sleep, indicating an inferior sleep quality. Optimisation of this schedule might diminish this impact and could contribute to a reduction of the cardiovascular disease risk among shift workers. (J Occup Health 2001; 43: 32-38
The Community Assessment of Psychic Experiences:Optimal cut-off scores for detecting individuals with a psychotic disorder
OBJECTIVES: The need for a brief screening tool for psychosis is widely recognized. The Community Assessment of Psychic Experiences (CAPE) is a popular selfâreport measure of psychosis, but a cutâoff score that can detect those most likely to fulfill diagnostic criteria for psychotic disorder is not established. METHODS: A caseâcontrol sample from the Genetic Risk and Outcome of Psychosis Project study (N = 1375, healthy individuals, n = 507, and individuals with a psychotic disorder, n = 868), was used to examine cutâoff scores of the CAPE with receiver operating curve analyses. We examined 27 possible cutâoff scores computed from a combination of scores from the frequency and distress scales of the various factors of the CAPE. RESULTS: The weighted severity positive symptom dimension was most optimal in detecting individuals with a psychotic disorder (>1.75 cutâoff; area under the curve = 0.88; sensitivity, 75%; specificity, 88%), which correctly identified 80% of the sample as cases or controls with a diagnostic odds ratio of 22.69. CONCLUSIONS: The CAPE can be used as a first screening tool to detect individuals who are likely to fulfill criteria for a psychotic disorder. The >1.75 cutâoff of the weighted severity positive symptom dimension provides a better prediction than all alternatives tested so far
